Now Playing Tracks

Bye Windows, hello Linux

More and more of my servers are being migrated to Linux, a notable one is my firewall. I have used TMG for many, many years, ever since MS released that product as “ISA Server” up to “Forefront TMG” 

Since Microsoft announced that they won’t be releasing new versions of TMG it was time for me to look for alternatives. After some searching I decided to go for a linux solution with the use of some (open source) Windows tools

I’ve installed Ubuntu server, the LTS release and used fwbuilder to create a nice firewall using their gui. Of course there was still a lot of configuring to be done with Ubuntu, but I got it working.

For application publishing I’m now using Web Application Proxy, which is part of Windows Server 2012 R2. This allows me to publish a few apps I got running here in a secure manner.

I’m quite happy with this change overall. It was quite a bit of work, but the end result is a nice one.

Bad luck strikes… I broke my wrist

During a skating run I fell backwards and broke my wrist on the ice. I got a nasty fracture with my wrist and this will need cirgury to get it straightened out.

The ice skating facilities had evening perfectly arranged, they took me to the traumatologist by ambulance, there they straightened out my wrist somewhat and put it into a cast„, this though didn’t doo too much good in the long run.

The cast was too tight and last night while screaming of pain we decided to go to the clinic here and they saw immediately what was going on. The cast has been replaced, surgery has been scheduled for next Monday.

Although an accident like this is rather painful the recovery time I have been told can be quick. In about 6 weeks I should be rid of the worst part.

Ill update this post once I know more.

Sharing mobile internet with your tablet

Left: Samsung Galaxy Tab 3; Right: Samsung S III Mini

Nowadays you can buy tablets with 3G on them, allowing you to stick in a SIM card with a mobile data subscription on it. This rather pricey approach got me thinking when I was about to buy my new tablet a few days ago.

I thought by myself… I have internet on my smart phone. Should I get 3G/4G on my tablet now as well? Then it hit me, didn’t have my mobile phone a feature called ‘internet tethering’? Yes, it has!

What is tethering?

Tethering allows you to share your mobile internet via either Bluetooth,  WiFi or even a simple USB cable. Most newer mobile smartphones have this feature. Once setup, you can use a different device (like a tablet, or laptop) to connect to it and use it’s mobile internet.

Setting up Bluetooth tethering is ridiculously simple. Just enable it in your Bluetooth settings, pair the 2 devices and you’re good to go! That’s it!

My new tablet, with mobile internet, without 3G

I ended up buying the Samsung Tab 3 tablet, which goes nicely together with my Samsung Galaxy SIII mini.

My father bought me a nice cover for it, so I can take it along when I’m on the road. I have Internet wherever I go and everything works perfectly fine. Best of all, this saved me at least about 200 USD in expenses for buying the tablet and a subscription with the phone company.

So if you’re looking for using your tablet on the go with a mobile internet connection, your phone might already have everything you need :)

Take care of that battery

A friend of mine had an UPS and told me… ‘I frequently discharge the battery to keep it in top condition…’ and I told him: “I guess you’re replacing your battery of your UPS in about 3-6 months…” I was right, his shiny new UPS battery died 2 months later.

The ‘discharge to zero’ myth has all to do with NiCad batteries. These batteries from the ‘stone age’ did indeed need a complete discharge to avoid ‘charge memory’. Li ion batteries do not have this problem, and lead acid batteries (the one in your car and UPS) don’t have these either.

So if you have a modern battery in your device…

  • Never discharge completely, it puts a lot of strain on your battery
  • Recharge frequently and keep it topped off
  • Keep batteries at room temperature if at all possible

And if your battery is dead, don’t throw it away with the rest of the garbage but let it be recycled.

2014 is coming, and it will change a lot!

Here at my place we are now celebrating the final hours of 2013. We didn’t win the lottery this year, nor did we have much luck with other things so 2014 is the time to set sails into a new direction.

As far as software development goes, I’ll be using more cloud platforms and will be more going into the digital sales of software & services and less for projects that are privately funded. This way we are going to try to setup a more continues business model that is less dependent on a relatively small number of customers.

As for my private life, I’ll be continuing with the things I already started in 2013, lose more weight, work on my health and strengthen my social network here in Chile.

I wish everyone a joyful and prosperous 2014, may it bring you happiness and if needed, change :)

Greets,

If anything else fails…. overheat! … that is what my poor PC must have been thinking yesterday.
As you can see in these pictures, the cause was a bit of a dusty PC… combine this with 2 broken ventilators and you’ve got a recipe for disaster. 
A big thanks to Guido helping me out to get my poor PC back running last night. It was a lot of work but we’ve got everything back up & running. The machine is stable and working correctly :)
